Yes i intend to race the bike , i thought i could bring it back to life seeing as it's left in a garage collecting dust .

We can get 100LL avgas here , you get a learners licence for micro lights and permision to buy avgas !

What head volume would be good on a 300 running avgas ?
Seeing as i like to fiddle with the bike i will be raising compression soon and then dyno it afterwards .
